Mistake-aware practice

Read the common mistake below before starting. Watch for that situation during the round rather than relying on trial and error.

Your goal

Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle.

Step by step

1. Select an editable cell.
2. Enter a value using the keypad or keyboard; Notes stores candidates.
3. Read the region, cage, arrow or outside clues alongside the normal constraints.
4. Check entries verifies the completed board; Undo reverses your last input.
5. New puzzle selects another included puzzle.

Controls

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game.

A useful example

A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction.
